The BMR for a man in his 20s is about 1,700 calories per day. If 204 of those calories should come from protein, about what percentage of his diet should come from protein?

Answer 1

Estimate like this:

200/1700 = 2/17 = 0.11674 = 11.67%

Answer 2

Well, estimate for the first two steps, and then divide and convert.

Answer 3

If you are estimating to get 2/17, and then using a calculator to divide, why not just divide 204/1700 to get .12 or 12%

(Some of us old timers actually had to memorize the 12 times table.
I recognized 204 = 120 + 84
120 = 10x12
84 = 7 x 12
so 204 = 17 x 12
then 204/1700 = 204/17 * 1/00 = 12/100 = .12 or 12%

Answer 4

Clearly, I'm not a math nerd!!!
